NanaWall^® SL45: The Monumental Folding/Paired Panel Aluminum System

Technical Description SL45:

The SL45 is a monumental, standard aluminum folding system designed to provide an opening glass wall or storefront up to 36' wide and a paired panel system for unlimited total width; see Maximum Size Chart. The folding system is available in various configurations utilizing one to twelve panels; see elevation drawings. The option exists for swing entry/exit panel(s), but note panel size constraints with a swing panel not hinged to a side jamb. There are many design possibilities; units can be either: all inward-opening or all outward-opening; some panels inward-opening and some panels outward- opening; panels can be center-pivoted; (see details in section drawings).

Frame and Panels

The nominal extruded aluminum frame and panel thickness is 1 3/4" (45 mm); see section drawings. Standard finishes include clear anodized, dark bronze anodized or white powder-coated; custom finishes are available from a range of over two hundred RAL powder coated finishes and many kynar finishes; see Aluminum Finish Options in the General Introduction.

Panels are pre-assembled, and all pins and screws needed to assemble frames are provided. On a folding pair of panels hinged to a side jamb, the panel hinged to the side jamb is 2" (52mm) narrower in nominal width than the other panels.

Besides the raised sill that matches the frame finish, various flush sills (shown in section drawings) are available as an option in a clear or dark bronze anodized finish.

Glazing

Units can be supplied either glazed with 1/4" (6 mm) single tempered or laminated; or 3/4" (20 mm) clear insulating tempered or insulating Low-E tempered glass or open. If supplied open, standard glass stops and "dry" glazing gaskets supplied are for a glass thickness of 1/4" (6mm) for single-glazing or 3/4" (20 mm) for double-glazing. Glass stops for other glass thickness are available as an option; see Glazing in the General Introduction.

Weatherstripping

All weatherstripping (consisting of EPDM or brush seals) is provided for sealing between panels and between panel and frame; see section drawings.

Sliding/Folding Hardware

For sliding and folding each pair of panels, a patented, load-bearing, upper-running carriage is attached to the upper corner of a panel; see section drawings. Attached to the lower corner is a lower-running carriage as a guide. The double pair, twin-tandem, upper-running carriage is constructed to ensure even pressure distribution on all four rollers. Rollers have sealed bearings and are coated with toughened Polyamide to ensure sound-free running and optimal resistance to extreme. Two to four patented hinges per connection are provided to connect panels together and to connect panels to frames. Hinge finish would be closest powder coat match to panel profile.

Locking Hardware and Handle Options

For each pair of folding panels and on the swing panel(s), if any, provided is two point locking hardware consisting of top and bottom Polyamide capped locking rods operated by a 180º turn of a flat handle. Handle finish would be closest powder coat match to the panel profile color.

If there is a swing panel, there are the following additional hardware options on the main entry panel:

1. Multi-point Locking. Consisting of lever handles on both sides, a Schlage compatible lockset, lockable latch, deadbolt and rods at the top and the bottom. Depression of handles withdraws latch, lifting of handles engages rods and turn of key or thumbturn engages deadbolt and locks.
2. Deadbolt Lock. ADA approved nylon pull handles on both sides with deadbolt(s) operated by a lockset. Turn of key or thumb turn operates lock. Lockset option of having key operation on both sides. To keep the panel closed, a door closer should be field installed, but note that a door closer can only be installed for a swing panel that is attached to the side jamb.
3. No Hardware. For panic hardware to be installed by others, the main entry panel can be supplied with no locking hardware.

If a unit is inward opening and there is no swing panel, an option to enable a unit to be opened from the outside is to provide on the folding pair to be opened first: Two point locking hardware consisting of top and bottom Polyamide capped locking rods operated by a 180º turn of a L-shaped nylon handle on the inside and a flat handle on the outside. Lockable with a lockset. Turn of key or thumb turn operates lock.

Nylon lever and L-shaped handle color is available in white, dark brown or gray. Solid brass lever handles are available in an oil rubbed bronze or satin nickel finish.
